 /**
  * A <code>ServiceEvent</code> listener that does not filter based upon
  * package wiring. <code>AllServiceListener</code> is a listener interface
  * that may be implemented by a bundle developer. When a
  * <code>ServiceEvent</code> is fired, it is synchronously delivered to an
  * <code>AllServiceListener</code>. The Framework may deliver
  * <code>ServiceEvent</code> objects to an <code>AllServiceListener</code>
  * out of order and may concurrently call and/or reenter an
  * <code>AllServiceListener</code>.
  * <p>
  * An <code>AllServiceListener</code> object is registered with the Framework
  * using the <code>BundleContext.addServiceListener</code> method.
  * <code>AllServiceListener</code> objects are called with a
  * <code>ServiceEvent</code> object when a service is registered, modified, or
  * is in the process of unregistering.
  *
  * <p>
  * <code>ServiceEvent</code> object delivery to
  * <code>AllServiceListener</code> objects is filtered by the filter specified
  * when the listener was registered. If the Java Runtime Environment supports
  * permissions, then additional filtering is done. <code>ServiceEvent</code>
  * objects are only delivered to the listener if the bundle which defines the
  * listener object's class has the appropriate <code>ServicePermission</code>
  * to get the service using at least one of the named classes under which the
  * service was registered.
  *
  * <p>
  * Unlike normal <code>ServiceListener</code> objects,
  * <code>AllServiceListener</code> objects receive all
  * <code>ServiceEvent</code> objects regardless of whether the package source
  * of the listening bundle is equal to the package source of the bundle that
  * registered the service. This means that the listener may not be able to cast
  * the service object to any of its corresponding service interfaces if the
  * service object is retrieved.
  *
  * @see ServiceEvent
  * @see ServicePermission
  * @ThreadSafe
  * @since 1.3
  * @version $Revision: 1.10 $
